Three boring sounds beat any filter
Take a shot of someone putting a cup down on a table, with only the camera's own audio. Add three things:
- Room tone under the whole scene, so the space has a floor and the cuts do not drop into digital silence.
- The cup contacting the table, placed one or two frames *before* the visual contact. We accept sound slightly early far more readily than sound slightly late, so early reads as perfectly synchronised.
- A quiet cloth layer for the arm moving.
None of that is glamorous. It does more for how expensive the shot feels than any filter, grade or transition you could apply. Perceived production value comes largely from things having a sound at all — silence where a sound should be is what registers as amateur, even to viewers who could not name what was missing.
The same holds for motion graphics. A transition with no sound reads as a glitch. One short whoosh with a low thump on the landing frame makes a logo animation feel deliberate, and it is the thump doing the work, not the whoosh.
The honest limit: layered sound design on a video that will be watched muted in a feed is wasted labour. Know where the thing plays before you spend an evening on foley.
Cutting music without it sounding cut
Music has structure, and the joins are where you can cut.
- Cut on a downbeat — the first beat of a bar — not wherever the timeline happens to sit.
- Cut at a section boundary. A drum fill leading into a new part is an invitation.
- To shorten a track, remove a whole number of bars, usually four or eight, and crossfade across the transient. Removing three and a half bars is what makes edited music sound wrong even when nobody can say why.
- To end a track, do not fade out over three seconds beneath your final line. Find the last hit and let it ring.
Choose music for its energy curve against your video's, not because you like the song. A track that builds at 0:40 is useless under a piece whose point lands at 0:12.
Ducking
Music under speech should drop 6–12 dB while someone talks and come back after.
Automatic duckers exist — Resolve's Fairlight has one, Premiere's Essential Sound panel has Auto-Duck, and Audacity has an Auto Duck effect. Doing it by hand with volume keyframes usually sounds better, because you can start the dip slightly before the first word and release slowly afterwards.
Set the release long, around 400–800 ms. A short release makes the music pump up between every sentence, which is more distracting than music that was simply too loud.
And most amateur mixes have the music too loud, for a specific reason: the editor has heard the voiceover fifty times and their brain fills in the words. Check on a phone speaker in a room with some noise in it. That is where it will actually be heard.
Licensing, told straight
"Royalty-free" means you do not pay per play. It does not mean free, and it certainly does not mean uncopyrighted. Somebody owns it.
Three situations people conflate:
- Licensed music. You bought a licence, from a subscription library or as a one-off. Read the term. Some libraries let you keep using videos published while you were subscribed; others do not, and your back catalogue becomes unlicensed the month you stop paying. Check that clause before you build a channel on a library.
- Creative Commons music. Free, and conditional. CC-BY requires attribution in the form the licence specifies. Skip the attribution and you are infringing, licence or not. Some CC licences forbid commercial use or derivative works, which includes cutting the track.
- "No copyright music" found on YouTube. Usually a lie, frequently reuploaded from a library, and the safest assumption is that it will be claimed.
Content ID is not copyright law. It is YouTube's automated matching system, comparing your audio against registered recordings. A claim can and does appear on videos with a valid licence, because the rights-holder registered the track and the matcher does not know about your receipt. You dispute it with the licence.
The practical habits: keep every licence PDF and invoice in the project folder alongside the video file, and check whether your library requires you to whitelist your channel ID *before* uploading. Skipping the whitelist step is the most common cause of a claim on properly licensed music, and it is a two-minute job you can only do in advance.
Sources that are genuinely safe and free: the YouTube Audio Library (per-track attribution flags, cleared for YouTube), Pixabay music, Free Music Archive and ccMixter (read the per-track licence), Incompetech (CC-BY — attribute it properly). For effects, Freesound, again with per-sound licences that vary.
Building a small sound-effects habit
You do not need a library subscription. Record your own: a door, a zip, a kettle, footsteps on three different surfaces, coins, paper, a chair. Ten minutes with a phone gives you a folder of things nobody else has, and cloth and footstep layers are the two you will reach for constantly.
Name the files properly the first time. An unsorted folder of recording_047.m4a is a folder you will never open again.
Today
Take a ten-second clip you have already edited. Lay room tone under all of it. Add exactly one foley hit at the most obvious physical action. Listen with and without. That comparison is the argument.
